To calculate the ideal mechanical advantage of a lever divide the input arm by the output arm.
Mechanical advantage is the amount by which a machine can multiply an input force, calculated by dividing output Force in newtons by input force in newtons, while the ideal mechanical advantage is the mechanical advantage of a machine that has no friction, calculated by dividing the input distance by the output distance.
Answer:
A. Time Division multiple Access (TDMA)
Explanation:
Time-division multiple access (TDMA) is a channel access method for shared-medium networks
It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using its own time slot.

Answer: The light is slowed down by the prism, but the different wavelengths of light are all slowed down a different amount by the prism.
Explanation:
What happens here is that white light passes from a medium with an specific index of refraction (air) to another medium with a different index of refraction (the material of which the prism is composed).
Then, when light passes from a medium to another, its speed changes causing the deviation of the beam of light. However, we are talking about white light that is composed of different wavelenghts. So, since the frequency of light remains costant when passing from one medium to another, the different wavelengths change as a result of the change in speed.
This was first observed by Isaac Newton in the eighteenth century, when he found out that when a beam of light from the Sun, passes trhough a prism is decomposed in many different colors.
